United States Patent O This application is a division of my copending application Serial No. 714,418, tiled February 10, 1958, now U.S. Patent No. 2,936,508, granted May 17, 1960.

The invention relates to a thread pack adapted for treatment in preparation for or subsequent to, the spinning process and, in this particular case, for the dyeing,

bleaching, steeping, drying, steaming, impregnating, etc.

by means of liquid, vaporous or gaseous treatment agents.

In order to dye, for instance, Wool, it will be as a rule reeled on proper reels to form banks having a length of approximately 60 cms. and the banks will be moved to and fro in a correspondingly large vessel containing the dye bath. The treatment by means of other liquids, e.g. for draining or bleaching is similarly done in other large vessels. Stearning, drying, etc. requires other equipment and other treatment methods.

Yarn will be dyed and treated similarly to wool by moving it to and fro in the dye bath etc., in Vthe form of banks, or in a state Wound upon a metal tube insofar as it has not yet been treated as an unspun bunch of spinning material the yarn body being moved through the treatment agent, the treatment may also be effected by passing or pressing the treatment agent through the yarn body. Unobjectionable and uniform dyeing of wool in the form of a cross wound bobbin or the like, usually wound on a metal tube, is hardly obtainable even by means of the high pressure method.

The invention aims at creating a homogeneous and loosely built up thread pack adapted to be formed easily from any length of thread, to be unwound, without any entanglement, down to the last portion of the thread, allowing, in addition, not only the omission of the reeling with its troublesome skeining by hand of the bunches dividing up the hanks and the windings of the bank to a bobbin or a ball before the use of the wool or the yarn, but allowing also to carry out the complete subsequent treatment required for the spinning of the respective thread up to its being ready for use, without any change in its shape or in its spin casing.

For this purpose, the thread pack, according to the invention, consists of rectangular, preferably square thread layers directly lying one upon the other without any separating leaf and formed of oblong helicoidally shaped thread coils overlapping each other in the manner of scales or tiles, the direction in each layer is wound as compared with the preceding layer being turned through a certain angle, preferably by 90.

The thread pack is, as a rule, surrounded by a prismatic or cylindrical casing, the walls of which are permeable for the treatment agents (liquids, steam, and gases), as they consist of wide-meshed fabric, plait, perforated, plain, undulated, or projection carrying sheets and panels of anti-corrosive metal, plastic, or of absorbent textile materials.

Inside the casings, means are provided for keeping the thread layers in close touch with each other, eg. a holding member arranged to lay upon the uppermost thread layer.

In the case of all such thread packs, but particularly in the case of such as are Covered by a bag, a holding member may be inserted both underneath the lowest and above the uppermost thread layer. The bag may be rice provided with an annular shutting device well known per se, the device being adjustable downwards, according to the withdrawals of the thread, to close the upper holding member, this member allows easy withdrawal of the thread.

In this form, the thread pack to be treated with liquid and gaseous agents may also be built up as a small consumers pack for yarns and wool and having a contents of approximately 20 to 200 grams or of up to 2 kilograms as a pack of binding thread or as a harvest yarn thread pack.

Small consumers thread packs consisting of square thread layers with oblong helicoidal coils and with each subsequent layer being turned by with regard to the preceding one are known, but they are consumers packs exclusively having their thread layers separated by separating strips or the like to ensure a withdrawal of the thread without any entanglement, the strips to be joined in a complicated manner and which separating strips hinder `any uniform dyeing. In the case of the thread body according to the invention it has been found, that such yarn packs, of any size, may be used for the direct treatment in preparation for, and subsequent to the spinning of the thread, if the thread layers are laid directly one upon the other without any separating leaves.

The device for the formation of thread bodies of the said kind consists, as is substantially known with the small consumers pack already mentioned, of a thread guide rotating round a coiling mandrel, for winding the thread in helicoidal coils round the coiling mandrel, and of a deliver device stripping off the kthread coils from the free end of the coiling mandrel, the free end having an oblong cross section. Stripping otf is done with interruptions, the spaces thus formed between groups of thread windings being bridged by individual connecting thread sections. The coils are delivered to a guiding device, by Which they are brought to an arrangement in which they overlap each other, and `which device leads the individual tread layers directly and without the use of separating foils or the like to a prismatic receptacle. The deposition of the layers is done in a way that each subsequent layer is turned, with regard to the preceding one, by a certain angle, preferably by 90. This device is more fully described in my copending patent application Serial No. 714,418 and needs no further explanation.

Other features of the invention result from the claims.

Examples of execution of the thread body now will `be described in detail.

In the respective drawing FiG. l shows a schematic, perspective View of the construction of the yarn pack,

FIG. la shows a top view of the yarn pack,

FIG. lb shows a portion of the layers in a larger scale.

FIG. 2 shows a schematic top View of a thread pack provided with its casing and placed in a treatment tank;

FIG. 3 shows a schematic view of a thread pack provided with its casing and placed in a treatment tank;

FIG. 4 shows a top View of a thread pack covered by a holding member;

FIG. 5 shows a thread pack with a casing consisting of strip elements;

FIG, 6 shows a consumers thread pack;

FIG. 7 shows a bag-shape formation of the envelope for the thread pack.

The thread pack 1 (FIGS. 1, la and 1b) is built up by individual thread layers 2 superimposed one upon the other. Each layer consists of oblong helicoidal coils 3 overlapping each other in scale-like manner. Compared with the subsequent layer, the direction of the coils of each thread layer is turned by a certain angle. In the case of FIGS. 1a and 1b, the angle of displacement amounts to 90 resulting, under consideration of each 3 thread layer being kept square, in a prismatic thread pack of a square base. Instead, the turning of the direction of the subsequent thread layers may also be effected by `any other angle resulting, as shown on FIG. 2, in a cylindrical thread pack. In the case of this pack, the individual thread layers may have any rectangular shape.

For the treatment subsequent to the spinning process, the thread pack is covered by a casing 4 (FIG. 3), the walls of which are permeable for the liquid, vaporous, and gaseous treatment agents. For this purpose, the walls may be provided with perforations 5 of any shape or may consist of cage bars 6 or of `wide-meshed fabric or plait. The walls -rnay be plain or undulated or provided with stamped impressions and such like. They have to be of a material indifferent to theftreatment agents thus to consist preferably of anti-corrosive metal or of plastic indifferent with respect to the used liquids or the like.

The treatment of the yarn pack is effected in a suitable treatment tank 7 (FIG. 3), into which the treatment agent is let in through an inlet 8 and let out through an outlet 9, eventually under pressure. The treatment may also be effected in such a way that the treatment agent in the tank 7 remains at rest and that the yarn pack is moved through the treatment agent.

In order to guarantee, while the thread pack is being manipulated and moved, a close contact of the individual thread layers 1 with each other without the application of separating leaves or of a separating leaf-skeleton such as are applied in small packs, a holding member 12 (FIGS. 3 to 6) is put on the uppermost thread layer, by the weight of which the thread layers are slightly pressed the one against the other. This holding member may be placed in a square frame as shown on FIG. 3 or may consist of a ring as shown on FIGS. 4 to 6. The effect of its weight may -be `brought about also by weak springs.

In the form of the thread pack according to FIGS. 4 and 5, the casing consists of two strips 13 crossing each other on the bottom, each being led upwards at opposite sides of the pack, and each interlocking, at the upper edge, between two projections 14 of the ring-shaped holding member 12. The strips have a rigid spring action resulting in their being in close touch with the yarn pack and thus securing an unhampered movability of the holding member 12.

In the form shown in FIG. 7, the casing of the yarn pack consists of a stiff, wide-meshed plastic or wire netting bound together at the opening end or provided with an annular lock and with loops 15 at the corners for the manipulation of the body in the treatment tank.

It is obvious that, as a consequence of the loose and uniform structure of the yarn pack, the treatment agents passed through the pack will equally affect all parts of the thread, so that a uniform dyeing of the thread body in all its parts is possible as well as every other additional treatment, and this at the smallest expenditure of energy and time.

It is well known, to form yarns and the like to a thread pack in cans. This is done in that the thread is deposited, round a central and perforated metal tube, in individual circular coils, the diameter of which is smaller than the radius of the cylindrical sliver can, the circular coils overlapping each other. The dye bath will be pressed through the perforations of the tube and into and through the thread body. In consequence of this type of coiling, however, a bunch of threads is formed in the centre part, the Contact of the thread parts is considerably more tight and more close than in the outer part. Practice has proved, however, that the centre part of such a thread pack cannot be dyed in a uniform manner apart from the fact that `also the circular thread coils at the periphery of the thread pack are entangled by the passing of the dye bath, as these thread portions are not suiciently supporting each other. Contrary thereto, in the yarn body according to the invention, each part of the thread is evenly crossed both by its thread parts above and underneath, so that all thread parts are supported `by a uniform pressure and kept at a uniform tightness and distance, which not only ensures a uniform dyeing, but also prevents an entanglement with each other of the thread parts by the dye bath. The thread body according to the invention is wound and built up completely without any core.

The form of embodiment of the thread pack as shown on FIG. 6 is intended to serve both as a large and a small consumers pack. The envelope consists of a foil bag 16 provided with a holding member 12 upon the uppermost thread layer and with a corresponding holding member 12 inserted underneath the lowest thread layer. The purpose of the latter is to guarantee the mantenane of the cross section shape of the thread body also at the lower end of the pack. The upper opening end of the bag is provided with a well known clamping ring closure 1S, through which the thread 19 is withdrawn. As can be seen, the clamping ring closure can be attached at any height of the bag and is thus adjustable to a height close to and above the upper holding mem-ber 12 in accordance with the withdrawal of the thread and the sinking down of the holding member, in order to ensure a close touch of the holding member to the thread layers. The close lying together of the winding layers may be effected or assisted by spring elements. If the touch of the thread layers is to be loosened for the withdrawal of the thread or for `any other working operation, the whole pack or parts of its casing, e.g. the strips 13 (FIG. 5) may be shaken or put into vibration.

What I claim, is:

1. In a device for the treatment of thread in preparation of and subsequent to spinning, a thread pack consisting of interconnected rectangular thread layers directly without any separating leaves deposited one upon the other, each layer being formed of a single series of oblong helicoidally shaped thread coils, said coils being arranged parallelly to one another in overlapped scale like fashion within their layers, the coiling direction of the oblong coils in neighbouring layers being turned one with respect to the other by a certain angle, `and a casing surrounding said thread pack, the walls of the casing having perforations for allowing the liquid and gaseous treatment agents to freely pass into the yarn pack, means for keeping the rectangular thread layers in close contact with each other comprising a holding member lying under its weight on the uppermost layer, whereby the thread pack can be brought into and taken out of the casing and can be dyed and otherwise treated with liquid and gaseous agents in a quite uniform manner without any entanglement.

2. In a device according to claim 1, said holding member being ring shaped, the ring opening being adapted for pulling out the thread through it.

3. In a device according to claim 1, said casing having the form of two strips crossing each other at the bottom and being bent upwards with spring action along oppolying on the uppermost layer, having two oppositely arsite side walls of said thread body, said holding member ranged spaced projections engaging the free ends of said strips.
